How many bytes are in 1 gigabyte (GB)?

• A. 1,000,000,000,000 bytes
• B. 1,073,741,824 bytes
• C. 1,024,000,000 bytes
• D. 1,000,000,000 bytes

Answer: (D)

A gigabyte is typically defined as 1,000,000,000 bytes when using decimal notation. In many contexts, especially for storage devices, GB means 10^9 bytes, while the binary counterpart 1 GiB equals 2^30 = 1,073,741,824 bytes. Since this question uses the decimal definition of a gigabyte, the correct value is 1,000,000,000 bytes. The other options correspond to a terabyte (10^12 bytes), a nonstandard decimal amount, and the binary size for a gibibyte, not a decimal gigabyte.
